This is such a simple song I really don't know why people are over complicating it with
their chords. There are two ways to play this: with capo and without. Both sound good.
WITHOUT CAPO:
Tuning Standard

GminWhen she was just a Bbgirl
FmajShe expected the Cworld

GminBut it flew away from her Bbreach so
FmajShe ran away in her Csleep

And dreamed of
GminBbFmajC

GminPara-para-Bbparadise, Para-para-paradise, Para-para-paradise
FmajEvery time she Cclosed her eyes

GminWhen she was just a Bbgirl
FmajShe expected the Cworld

GminBut it flew away from her Bbreach
FmajAnd the bullets catch in her Cteeth
